winter solstice / 冬至キャンドルナイトは？

Today is the winter solstice day. I have been looking for information on ‘Candle Night‘ – a series of campaigns for saving energy by switching off all electric lights between 8-10pm on the summer and winter solstice day. It seems the campaign was finished in 2012 and is not happening today. Why?? It’s very nice to spend time with candle light!
